Is your feature request related to a problem? Please describe.

vscode supports adding multiple paths to flutter sdk, which allows us to switch between multiple versions of flutter and it works pretty well. I have set it up this way as answered in this stackoverflow thread but the problem is when we switch the version and when I look at the definition of any class, I see that it still points to the old SDK's code. The changes only gets reflected when we call flutter pub get

Describe the solution you'd like
So the solution I think is when we change the path to sdk the plugin should also call flutter pub get so that it points to correct class definitions.

Additional context

Heres a small demo describing the issue.
